Your experiences with teenaged children match my own.
My D17 and S14 have a lot of anger towards stbx.
I've been wondering lately how a R would work (not likely in my case), given that children carry such scars.
For example, STBX rang my kids last night and spoke to D17 first. When he was passed to S14, first thing stbx asked him was "Is your sister still being a cow?"
Imagine how hard it would be to get those relationships back on track if stbx and I were ever reconciled.
In short, just wanted to say thanks for this thread. It seems yet another important part of this process that we all need to work at.
